Popular Abstract in Swedish Allt liv på jorden har utvecklats i en vattenbaserad miljö. Proteiner och andra biomolekyler har därigenom anpassats i sin struktur och funktion till vattnets speciella egenskaper. För att kunna förstå biologiska processer måste vi studera hur biomolekyler växelverkar med det omgivande vattnet under fysiologiska betingelser. Detta är särkilt viktigt eftersom det flesta The results presented in this thesis demonstrate that the magnetic relaxation dispersion (MRD) technique can provide information of relevance to protein biophysics, magnetic resonance imaging and cell biology. By immobilizing proteins with covalent cross-links, intermittent protein dynamics on the previously inaccessible ns-µs time scale could be probed with MRD via the exchange of water molecule

Biometric identification is an important security application that requires non-intrusive capture and real-time processing. Recently, identification by vein patterns has been suggested as a promising alternative. In this paper we study the potential of Cellular Neural Networks implemented on a Field-Programmable Gate Array to handle the person identification based on hand veins in real time. With

Individual energy turnover rates can vary remarkably, even within a species. In this thesis I study the causes and consequences of this pronounced variation and show that individual energy turnover rates can be affected by a large number of factors. I here show that both the early conditions during the incubation period and prenatal levels of the hormone testosterone can have consequences on indiv

This dissertation investigates correlations in finite Fermi systems. The atomic nuclei is the mainly studied system but also other systems, like superconducting metallic grains and cold Fermionic gases are considered. The dissertation comprises of five original papers. Paper I and II investigates the autocorrelation function of the difference between experimental and theoretical nuclear masses.

This paper describes a method to determine the extinction cross section for a very large bandwidth in the microwave region. The method is based on measurements of the radar cross section in the forward direction to calculate the extinction cross section. The method is applicable to samples of arbitrary shape and composition. Coherent background subtraction and time domain gating is used for the fr

The year 2007 was an extraordinary year for the US Patent System. In a response to far reaching proposals for significant changes in substantive and procedural patent law the House of Representatives adopted the Patent Reform Act in September and the debates were heating up again. Moreover, the U.S. Supreme Court turned its attention to patent issues delivering three major patent judgments and gra
